L-type coaxial plug connector

Abstract

An L-type coaxial plug connector adapted to be connected to one end of a coaxial cable has a crimp sleeve on the outer sheath of the coaxial cable and adapted to be collapsed so as to fix the coaxial cable to the plug connector. The outer shell has a cylindrical portion holding a dielectric member in which the central terminal is fixed, a cylindrical outer conductor fitting portion adapted to be inserted into the boundary between the inner dielectric layer and the outer conductor of the coaxial cable, and an intermediate portion which extends axially from a portion of the upper circumferential edge of the cylindrical portion so as to connect the portion of the cylindrical portion to the corresponding portion of the lower circumferential edge of the outer conductor fitting portion, such that the axes of said cylindrical portion and the outer conductor fitting portion extend in parallel with each other. The intermediate portion has a U-shaped arm portion which extends from the intermediate portion in the direction perpendicular to the axis of the cylindrical portion, and a cover portion which is adapted to cover the adjacent open end of the cylindrical portion when the intermediate portion is flexed substantially orthogonally towards the U-shaped arm portion.

What is claimed is: 
     
       1. An L-type coaxial plug connector comprising: a central terminal adapted to be connected to the core conductor of a coaxial cable so as to constitute a part of the core conductor of the coaxial line to be formed;   an outer shell adapted to be connected to the outer conductor of said coaxial cable so as to constitute a part of the outer conductor of the coaxial line to be formed;   and   a crimp sleeve on an outer sheath of said coaxial cable and adapted to be collapsed so as to fix said coaxial cable to said plug connector;   wherein said outer shell has a cylindrical portion holding a dielectric member in which said central terminal is fixed, a cylindrical outer conductor fitting portion adapted to be inserted into the boundary between the inner dielectric layer and the outer conductor of said coaxial cable, and an intermediate portion which extends axially from a portion of an upper circumferential edge of said cylindrical portion so as to connect said portion of said cylindrical portion to the corresponding portion of the lower circumferential edge of said outer conductor fitting portion such that the axes of said cylindrical portion and said outer conductor fitting portion extend in parallel with each other,   said intermediate portion having a U-shaped arm portion which extends from said intermediate portion in the direction perpendicular to said axis of said cylindrical portion, and a cover portion which is adapted to cover an adjacent open end of said cylindrical portion when said intermediate portion is flexed substantially orthogonally towards said U-shaped arm portion.   
     
     
       2. An L-type coaxial plug connector according to claim 1, wherein said U-shaped arm portion has arms which extend to a position where said outer conductor fitting portion is located when said intermediate portion of said outer shell is flexed, said arms being adapted to be received in the gap between said outer conductor of said coaxial cable and said crimp sleeve so as to be pressed onto said outer conductor of said coaxial cable when said crimp sleeve is collapsed, thus serving as an auxiliary connector for connecting said outer conductor. 
     
     
       3. An L-type coaxial plug connector according to claim 1, wherein said outer conductor fitting portion is provided in the outer peripheral surface thereof with annular grooves and ridges. 
     
     
       4. An L-type coaxial plug connector according to claim 1, wherein said outer conductor fitting portion is provided in the inner peripheral surface thereof with annular grooves and ridges. 
     
     
       5. An L-type coaxial plug connector according to claim 3 wherein said outer conductor fitting portion is provided in the inner peripheral surface thereof with annular grooves and ridges.
